Use the equation to answer the following question y=(x-3(x+2)/(x+4)(x-4)(x+2)
a. find all points of discontinuity
b. determine whether each point is removable(hole) or non-removable (vertical asymptote)
c. find the equation of the horizontal and vertical asymptotes for the rational function if any

See below

Step-by-step explanation:

The given rational function is;

The given function is not continuous where the denominator is equal to zero.

The function is discontinuous at

b) The point at x=-2 is a removable discontinuity(hole) because (x+2) is common to both the numerator and the denominator.

The point at x=-4 and x=4 are  non-removable discontinuities(vertical asymptotes)

c) The equation of the vertical asymptotes are x=-4 and x=4

To find the equation of the horizontal asymptote, we take limit to infinity.

The horizontal asymptote is y=0
